Optimate Chargers

[matthew69]

The Cerb let me down for the first time yesterday, near flat battery after not driving it for three weeks. Started first time being jumped.

Have put it on charge with in car optimate trickle charger.

Anyone have any idea on how long they take from flat to fully charged.

Thanks

I think you will need to use a proper bettery charger to get the battery up, the optimate just tops up the battery when the voltage drops.

Yes, an Optimate is not a trickle charger but a conditioner (mA applied only if required, then switched off). If it charges your flat battery at all, it could take several days. Conditioners are really for keeping normally-charged batteries happy! IE best time to use it was 3 weeks ago!!

At least it won't happen again!
